“So, as those who have been chosen of God, holy and beloved, put on a heart of compassion, kindness, humility, gentleness and patience” (Colossians 3:12) In the previous section Paul began by reminding us to die to self, put off the old self and now contrasts those instructions with putting on the new man. He goes on to explain exactly what that looks like and how. “Put on love” and “Let the word of Christ richly dwell within you, with all wisdom teaching and admonishing one another with psalms and hymns and spiritual songs, singing with thankfulness in your hearts to God. Whatever you do in word or deed, do all in the name of the Lord Jesus, giving thanks through Him to God the Father.” (Colossians 3:16-17)
Finally, Paul concludes the chapter with instructions that turns the culture on its ear. The man of the house is to love and gently care for his wife and children. No longer should he rule with an iron fist, inflicting fear and intimidation from his position of power. Furthermore, slaves and masters are to treat each other with respect (1 Timothy 6:1-2 and Colossians 3:22). Essentially Paul is telling the church in Colossae (and to us) that we need to change our perspective. We are no longer masters (of self) but rather slaves to our Lord Jesus Christ. From here on out, all that we do is for Him. Whatever we do must be our best effort because He is our master and we desire to do our best because for our love for Him.
